SSL Certificate FAQs
Are SSL certificates valid forever?
Certificate authorities set expiration dates and review certificates regularly. Since a legitimate site could later become a phishing site, certificates are not issued with permanent validity.
How do I choose an SSL certificate?
Choose a certificate based on the validation level (DV, OV, or EV) and domain coverage your application needs. Personal websites can use DV certificates; OV and EV certificates require a registered business.
What is the difference between paid and free SSL certificates?
Paid certificates offer stable service and broader browser trust. Free certificates may last only one or a few months and can be revoked, which may make a website inaccessible.
Why is my domain validation still pending?
1. Check that the CNAME record is correct and has propagated. 2. Allow 5–10 minutes after submission for verification. 3. If the issue continues, contact support.
Can I add domains to a multi-domain SSL certificate later?
Domains are set when a multi-domain certificate is issued and cannot be added or changed later. Confirm all domains before binding.
